Hashcat seems to be slow? - moonclair - 03-21-2021

Hi! I have amd RX570, i followed these steps https://hashcat.net/faq/wrongdriver
And I still getting this: "Update your backend API runtime / driver the right way"

Wiki says that free Driver Fusion can be used to install display drivers, but it no longer works, so I used Driver Booster


Here's what i get. I receive 20000 H/s, I assume i would get more

Code:
OpenCL API (OpenCL 2.1 AMD-APP (3075.13)) - Platform #1 [Advanced Micro Devices, Inc.]
======================================================================================
* Device #1: Ellesmere, 8128/8192 MB (6745 MB allocatable), 32MCU

OpenCL API (OpenCL 2.1 AMD-APP (3224.5)) - Platform #2 [Advanced Micro Devices, Inc.]
=====================================================================================
* Device #2: Ellesmere, skipped

Minimum password length supported by kernel: 0
Maximum password length supported by kernel: 20

Hashes: 1 digests; 1 unique digests, 1 unique salts
Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates

Applicable optimizers applied:
* Optimized-Kernel
* Zero-Byte
* Single-Hash
* Single-Salt
* Brute-Force

Watchdog: Temperature abort trigger set to 90c

Host memory required for this attack: 626 MB

Cracking performance lower than expected?

* Create more work items to make use of your parallelization power:

RE: Hashcat seems to be slow? - Snoopy - 03-22-2021

if you want to test or get your probably best speed try benchmarking first

hashcat -b -m 12500

do 3-4 runs and get the expected full-speed of your hardware, quick test with a normal pc

Hashmode: 12500 - RAR3-hp (Iterations: 262144)

Speed.#1.........:    1420 H/s (67.45ms) @ Accel:32 Loops:16384 Thr:1 Vec:8
Speed.#3.........:      192 H/s (69.96ms) @ Accel:2 Loops:16384 Thr:64 Vec:4
Speed.#*.........:    1612 H/s

the 1420 hashes or 192 hashes is the best speed "i" can expect for GPU, CPU when attacking mode 12500

so just try it for yourself and see whether or not  your actual cracking speed of 20300 hashes is near your best benchmark for -m 12500

if yes, then yes, this is the best speed you can expect, if not, maybe your mask of length 6 is still "to short" for parallel work on your gpu

be aware most hashmodes with high iterations are considered to be slow

It's actually not slow yet until hashcat says 'Estimated Time: Next Big Bang (> 10 years)' ))
